I’ve been adding content to pages – no problems. I added a couple of posts – again no problem I thought, until I go to the post page. The widgets aren’t over on the right hand side, they’re appearing at the bottom of the post – after the social buttons and the comment box – just above the footer.

On index page and other pages the widgets are behaving themselves properly.

OK – excuse the frequent updates but I’ve just found that the smiley is from the WordPress stats plug-in. Have disabled it but still have the widgets appearing at the bottom of posts so it wasn’t that.

I compared your css to standard css and couldn’t find any difference – the only difference I noticed is that your “Recent Posts” are listed with two symbols. As you can see here in this demo: http://www.kriesi.at/themes/newscast/ there should be only one list symbol per item.
